Question

我有这种阵列：

array {
    [0] => {"ID":"343","name":"John","money":"3000"}
    [1] => {"ID":"344","name":"Erik","money":"2000"}
    [2] => {"ID":"346","name":"Ronny","money":"3300"}
}

我想通过JSON将它从PHP读到JavaScript。如您所见，内部数组已按如下方式编码：

json_encode($a)

要从我的JavaScript代码中读取，我希望它使用以下语法：

"[0]" : "{"ID":"343","name":"John","money":"3000"}",
"[1]" : "{"ID":"344","name":"Eric","money":"2000"}",
"[2]" : "{"ID":"345","name":"Ronny","money":"3300"}",

我该怎么做？

Answer 1

在标题中，您要求如何使用JSON多维数组进行编码。我将假设这是你真正的问题，因为你的问题机构会提出不同的问题。假设您有一个数组$arr，请不要在每个内部数组json_encode()上调用$a。

相反，只需调用json_encode($arr)，它将编码整个数组，包括内部数组。

$arr = array (

    array ("ID" => "343", "name" => "John", "money" => "3000"),
    array ("ID" => "344", "name" => "Erik", "money" => "2000"),
    array ("ID" => "346", "name" => "Ronny", "money" => "3300")

);

$j = json_encode($arr);

$j将是这样的：

[{"ID":"343","name":"John","money":"3000"},
{"ID":"344","name":"Erik","money":"2000"},
{"ID":"346","name":"Ronny","money":"3300"}]

您可以使用jQuery.parseJSON()轻松解析此问题。然后，您可以简单地遍历解析后的数组，从内部数组中获取所需内容。

var arr = jQuery.parseJSON('[{"ID":"343","name":"John","money":"3000"},{"ID":"344","name":"Erik","money":"2000"},{"ID":"346","name":"Ronny","money":"3300"}]');

for(var i = 0; i < arr.length; i++) {
    var a = arr[i]; // Inner array.

    console.log(a.ID);
    console.log(a.name);
    console.log(a.money);
}

Answer 2

$arr = array(
      '[0]' => '{"ID":"343","name":"John","money":"3000"}',
      '[1]' => '{"ID":"344","name":"Erik","money":"2000"}',
      '[2]' => '{"ID":"346","name":"Ronny","money":"3300"}'
     );
echo json_encode($arr);
